May 3l, 1955 c. J. PAULsoN JOURNAL Box Filed Oct. 7. 1952 United States Patent O JOURNAL BOX Charles J. Paulson, Iowa City, Iowa Application October 7, 1952, Serial No. 313,512

1 Claim. (Cl. 10S-221) The present invention relates to new and useful improvements in journal boxes for use particularly on the trucks of railroad freight cars and has for its primary object to provide, in a manner as hereinafter set forth, a box of this character comprising a novel construction and arrangement whereby the journal may be expeditiously removed and replaced without the necessity for jacking up the car, as at present, resulting in a great saving in time and labor.

Other objects of the invention are to provide a journal box of the aforementioned character which will be comparatively simple in construction, strong, durable, compact and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specication, taken in connection with the accompanying drawing wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure l is a view in side elevation of a truck equipped with journal boxes constructed in accordance with the present invention.

Figure 2 is a vertical sectional view, taken substantially on the line 2-2 of Figure l.

Figure 3 is a View in horizontal section, taken substantially on the line 3-3 of Figure 2.

Figure 4 is a side elevational view, showing the method of removing a journal from the box.

Referring now to the drawing in detail, it will be seen that reference numeral designates generally a truck comprising the sides 11. Mounted beneath the end portions of the truck sides 11 are journal boxes 12 which embody the present invention. Conventional journals 13 on the ends of axles 14 are rotatable in the boxes 12, said axles having xed thereon adjacent said boxes the usual anged wheels 15.

Each box 12 includes a stationary upper section 16 which is open at its outer end and which has hinged thereon, as at 17, a vertically swinging closure 18. Mounted in the stationary upper section 16 of the box 12 is a brass 19 constituting a bearing for the journal 13.

The box 12 further includes a downwardly swingable lower section 20 the inner side of which is hingedly connected, as at 21, to the corresponding side of said upper section 16. The other or outer side of the lower section 20 is detachably secured to the corresponding side of the upper section 12 by a fastener in the form of a hinge structure 22. As shown to advantage in Figure 3 of the drawing, the hinge 21 and the fastener or hinge 22 are similar in construction, each comprising a removable pin or pintle 23 and 24, respectively. The pins 23 and 24 are secured in position through the medium of

cotter keys

25 and 26, respectively.

A longitudinal truss or bar 27 extends between the bottom of the lower journal box section 20 and the adjacent portion of the truck side 11. Apertured ears 2S depend from the lower section 20 of the journal box and extending therebetween is a removable pin 29. The pin 29 extends through an eye 30 on this end of the truss or bar 27 for detachably connecting said truss or bar to the journal box. A substantially similar joint or connection 31 is provide-d between the other end of the truss or bar 27 and the truck side 11. The bar 27 will support the box section 2i) in position beneath the upper section 16 in the event of loss of either of the

hinge pins

25 or 26.

It is thought that the operation of the invention will be readily apparent from a consideration of the foregoing. Briey, to remove the journals 13 from the boxes 12, one end of the truck 10 is elevated by placing beneath the sides 11 thereof, suitable jacks 32 (see Figure 4). The pin 29 is then removed for disconnecting the truss or bar 27 from the lower section 20 of the journal box. Of course, this is done on both sides. of the truck. The pins 24 are then removed after having extracted the cotter keys 26 for permitting the lower sections 20 of the journal boxes to swing downwardly on their hinges 21. The journals 13 are thus freed and the axle 14 may be rolled away on the wheels 15. Of course, to replace the journals the foregoing operation is substantially reversed.

Itis believed that the many advantages of a journal box constructed in accordance with the present invention will be readily understood and although a preferred embodiment of the device is as illustrated and described, it is to be understood that changes in the details of construction may be resorted to which will fall within the scope of the invention as claimed.

Having described the invention, what is claimed as new is:

In a railroad car truck comprising a side frame, a journal box mounted on one end portion of said side frame and depending therefrom, said journal box including complemental upper and lower sections, hinges compris' ing removable pins pivotally and detachably securing the lower box section beneath the upper section, and a safety bar having one end pivotally secured to the frame and its other end detachably secured at an intermediate point beneath the lower box section between the vertical planes of the hinges for retaining same in position should either of the hinge pins be lost.
